ARAPAHOE COUNTY, Colo. - Denver Broncos star linebacker Von Miller was arrested Sunday at the Centennial Gun Club on a failure to appear warrant.

Court records show Miller, 24, was arrested for not appearing at his court hearing on charges from last October when he was cited for careless driving, driving without a license and no proof of insurance.

A uniform summons and complaint document says the offense happened on the 12000 block of Easter Avenue in Foxfield, about four blocks from Miller's listed home address. The document does not elaborate on the nature of Miller's alleged careless driving.

Court records show Miller was scheduled for arraignment on Dec. 31, the day after the Broncos' final regular season game in Denver. He didn't attend the hearing and the arrest warrant was issued Jan. 2.

Arapahoe County Undersheriff Dave Welcher said his agency issues thousands of failure to appear warrant annually and focuses its resources on tracking down people with more serious warrants than a traffic infraction.

Walcher told 7NEWS that Miller went into the gun club Sunday and was found to have an outstanding warrant for his arrest.

An arrest document shows the Colorado Bureau of Investigation notified deputies that Miller was at the store. CBI conducts criminal background checks on people purchasing firearms, raising the possibility that Miller was flagged for the arrest warrant when he tried to buy a gun.

CBI spokeswoman Susan Medina said her agency cannot discuss firearm buyer background checks, because they are not public records.

Although Miller was arrested at a gun club, the arrest document shows he was unarmed when he was taken into custody.

Miller was booked and released on Sunday on a $1,000 bond, which records show was paid by his mother, Gloria Williams Miller. The Denver Broncos players had Sunday off from training camp.

His bond conditions require Miller to get permission from the court to travel out of state for this Saturday's away game against the Seattle Seahawks.

The Broncos issued a statement Wednesday afternoon after 7NEWS broke the story. The statement said, "We have been aware of the matter involving Von Miller’s failure to appear in court for traffic violations. It was reported to the league earlier this week and is being handled through the legal system."

Miller's representatives were scheduled to meet with league officials Thursday to formally appeal the suspension. The result of that hearing may not be known for a while.

George Atallah, assistant executive director of the NFL Players Association, has said Miller's case is not about testing positive for a performance-enhancing drug, according to the Denver Post.

In 2011, Miller tested positive for marijuana and amphetamines, according to sources who talked to the Post. As a result, Miller was placed in the league's intervention program.

According to the league's drug policy, a player in the intervention program can be found in violation if he misses a test or repeatedly shows up late for testing or counseling, alters the sample or demonstrates behavioral issues.

Mike Klis, a sports writer for The Denver Post, said the recent arrest may hurt Miller's ability to win his appeal of the suspension.

"If Von Miller is saying, 'Look, I'm responsible for my actions, and I'm accountable for my actions,' The NFL could say, 'Well, how responsible are you? Look at what just happened. You have this cloud hanging over your head and something else came up. Why should we believe you?'"
